27. Chiomara asychis Cramer (Fig. 27.) 



Biol. Ccnt.-Amer., lihopalocera, pi. 91, fig. 3, (1899). 



This species lacks the costal fold. It is another South and 

 Central American species, crossing the Mexican ])order into 

 Texas and Arizona. 



The valvae are asymmetric and very like those of the jjjenus 

 Thanaos. The uncus ends in a short beak; the scaphium is well 

 developed, set with ver,y fine short hairs outwardly; the girdle 

 of the tegumen is not symmetrical, the left side being extended 

 to meet the shorter valve; the right valve ends ventrally in a 

 spatulate projection extending beyond the dorsal lol^e, the 

 latter having a fluted outer margin; the left valve ends ventrally 

 in a triangular lobe serrate on the caudal margin, and projecting 

 beyond the dorsal lobe, the latter ending in a projection with a 

 round serrate outer margin; the aedoeagus is simple. 



2S. Thanaos gesta Herrich-Schaeffer (Fig. 28.) 

 Hiol. Ceiit.-.Ajner., Rhopalocera, pi. 91, fig. 9, (1899). 



This species is without the costal fold. It is from the West 

 Indi(>s, Central America and ]\Iexico, crossing the border into 

 Texas and Arizona. We believe Lindsey to be correct in i^lacing 

 it in the genus Thanaos. 



The uncus ends in a pair of hooks, the dorsal ridges of which 

 are serrate and also bear some small spines, at the base of these 

 there projects a second pair of smooth beaks; the scaphium is 

 developed and denticulate outwardly; the right valve ends 

 ventrally in a long slender rod and dorsally in a single rounded 

 projection; the left valve ends ventrally in a long tapering rod 

 and dorsally in a double rounded lo])e at right angles to the axis; 

 both valves have their dorsal and ajiical areas set with sharp 

 spines; the aedoeagus is simple but sharply curved up near its 

 apex. 



29. Timochares ruptifasciatus Plotz (Fig. 29.) 

 Biol. Ceiit.-Ainer., Rhopalocera, pi. 88, fig. 3, (1890). 



This species has ])oth costal fold and tibial tuft. 



It is from Mexico, and th(>re is a pair from the Ilunyon catch, 

 southwestern Arizona or southeastern California, in the Academy 

 Collection.
